What densities are mineral wool batt and board available in?

Mineral wool batt and board insulation is commonly found in various density ranges, and the correct answer reflects the most common densities for these materials. Densities of 3, 4, 6, and 8 lb/ft³ provide a suitable balance between thermal insulation properties and structural integrity. These densities are typical for ensuring good thermal performance, fire resistance, and sound absorption, which are key characteristics desired in insulation applications.

The higher density options within this range, like 6 and 8 lb/ft³, are often preferred for areas requiring greater noise control and thermal resistance. This combination of densities allows for versatility in applications including commercial and residential buildings, ensuring that the insulation material can meet specific performance criteria based on the intended use.

Other choices present density ranges that do not align with standard mineral wool specifications, indicating either lower or less common options.
